FreeHeat™ Perimeter Insulation System

Insulation in the right place saves you money, every day!

The investment in constructing a self-supporting shell allows Arctic Spas® to insulate differently than everyone else.

For our design inspiration, we didn’t have to look far, our homes in northern Canada provided us all we needed. We insulate the exterior walls, the floors and most importantly the attics of our homes and we tuck everything important to us within this insulated envelope.

Ambient heat from the pump penetrates the spa shell and heats the water. In winter this heat returns to the pump area in the event of a power loss. We have always believed that insulation below the water surface is of small value if the areas above and directly to the sides of the water are not adequately insulated (seriously, doesn’t heat rise?).

The “attic” of our design is our Mylovac cover, which at 5” of thickness and featuring a full-length baffle is capable of retaining even more of your energy dollars. Next, high density polyurethane foam is applied to the cabinet walls and lip underside to a thickness that stops heat loss. We finish off this insulation envelope with the same foam applied into our floor systems.

Then, we place all our equipment inside this cocoon, creating a perfect, stable operating environment.

More Innovation

Any barrier between the equipment and the shell will prevent heat transfer and cost you money. We have taken our insulation to the next level.

Already the best insulated cabinet in the world, our FreeHeat® Insulation system did not escape the exacting eye of our engineers. Our overlap door insulation design removes the last opportunity for heat loss and captures even more residual equipment heat.

To monitor this increased capacity for trapping waste heat, we have enabled our spa packs to take in internal cabinet temperature data and to activate the innovative RossExhaust™ system to balance the cabinet temperature when required.

The ability to balance and manage the cabinet air temperature is such a unique and valuable feature that we have secured a patent on this system. No other hot tub in the world has FreeHeat.

Lowest Running Costs

What does this mean for the spa owner though? Residual heat from our equipment, primarily our High Flow Energy Efficient motors, is allowed to penetrate through the fiberglass shell.

This maintains spa water temperature and eliminates many of the heater cycles that other designs, particularly foam-filled insulated designs have to run. Fewer heater cycles mean a lower power bill each and every month.

True Freeze Protection

One last benefit of the FreeHeat® design that we hope you never need is the ability of the spa water’s heat to keep the cabinet from freezing in a power outage situation. Without any insulation between the water and the cabinet, heat energy transfer can work in both directions. In our testing, and from anecdotal evidence, you have about 7 days, at -20ºC before freezing occurs within the cabinet and adding an alternate heat source (space heater, trouble light) can prolong this grace period indefinitely. Other brands can start to freeze within a few hours in these conditions.

Nice to have some margin for error, isn’t it?

OTHER SPAS: BEWARE!

Full foam cabinet does not allow heat from the motors to get through to help heat the spa water and makes spa repairs extremely difficult and expensive.

Heat cannot penetrate foam under spa cabinet and it has nowhere else to go but into the atmosphere – this effectively wastes your money.

Any barrier between the equipment and the shell will prevent heat transfer and cost you money.
